Everything You Need To Know About Block and Bleed Valves

Many industries depend on valves to properly regulate their fluid systems by using mechanical or electronic actuation to stop, throttle, restrict or permit a certain amount of fluid through a pipeline. Read on to learn more about block and bleed valves and how industries use them to help reduce the cost of maintenance.

What are Block and Bleed Valves?

Valves are generally designed to regulate fluid flow, whereas block and bleed valves are designed to isolate the fluid from specific equipment. For example, in the chemical industry, block and bleed valves are used frequently during maintenance and repairs to isolate equipment from flammable or toxic fluids. When cleaning or repairing a component in the chemical plant, companies can’t afford to shut down the plant entirely for the purpose of maintenance; instead, they use block and bleed valves to isolate the equipment that requires repairs. The block and bleed mechanism depressurizes the system and isolates a particular section for maintenance and repairs without interrupting the workflow. Block and bleed valves are widely used in the oil and gas, petrochemical and power generation industries to allow companies to isolate equipment without interfering with the ongoing process.

Different Applications for Block and Bleed Valves

While block and bleed valves are mainly used to isolate equipment for maintenance and repairs, they can be used in many different applications, such as:

  • Meter Calibration
  • Piping/ Instrument Isolation
  • Gauge Isolation
  • Instrument Drain
  • Prevent Product Contamination
  • Transmission and Storage
  • Chemical Injection Connection
  • Sample Connections

Features of Block and Bleed Valves 

When selecting block and bleed valves for your fluid systems, you should consider the temperature and pressure parameters you will need as well as any other fluid properties that could affect the valves. If you’re unsure as to which block and bleed valve is suitable for your process, talk to your manufacturer or supplier. Depending on the fluid properties and how the valve will be used, your supplier should be able to determine which product will best suit your objectives.
